I did not automate this process, but I did design tables with 5 felt colors and 5 background colors for a total of 25 color combinations. I've removed the characters and replaced them with empty chairs, which load dynamically (IE I hand edited each of the 30 image files per color scheme). I've posted them to my server as freeware.
Feel free to d/l them at
